UNITED STATES rATENroi-fm i `JOHN COOPER, "oruouxfr vERNou, OILING BOXES OFVERTICAL SUGAB-IVIILL i specification of Letters Patent No. 26,340,` datiifneeemb y To all whomit may concern:

Be it known that I, J OHN COOPER, of Mount Vernon, in the county of Knox and State of Ohio, have invented new and useful Improvements in the Mode of Giling the Boxes of Vertical Sugar-Mill Rollers; and I do hereby declare that the following is a full and complete description of the con struction and operation of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure l, is an elevation of one roller and boxes, Fig. 2 is a Vertical section of the same, Fig. 3, is a top view of theupper box, Fig. 4 is a top view of the upper head of the roller, upon the line X X in Fig. 2, and Fig. 5, is a cross section in the line Y Yin Fig. 2.

Sorghum, and other sugar mills, are usually constructed with vertical cylinders, such being much preferred to those that are horizontal, for obvious reasons, the chief of which, are, cheapness of construction, and their ready adaptation to horse or mule power.` But a great difficulty has hitherto been experienced in keeping the journals properly lubricated with oil, without the waste o-il becoming mixed with the juice of the cane, and thus injuring the flavor of the syrup. y

The nature of my invention relates, therefore, to the construction and arrangement of devices, by which this difliculty is entirely obviated. In setting forth the nature of my invention, I have represented but one roller, there being three generally used, but this one fully illustrates my invention.

A, represents the body of the roller, and B the shaft that passes through the center.

In Fig. 2, C C represent the heads of the cylinders or rollers. These may be separate, or cast solid with the cylinder. y

I) in Figs. 1 and 2, represents the gear, which lies above `the upper set of boxes. The oil hole, into which the oil is poured, is seen at a in Fig. 2.

E, E', represent the upper boxes, E be ing adjustable by means of the set screw F.

Below the upper plate Gr which forms a part of the frame work of the mill, and to which the upper boxes are attached, Vis

- placed the circular cup H. This cup is cast upon and forms a part of the head C. This cup encompasses the shaft B, being concentric therewith, as seen in Fig. 4, consequently,

all the` oil that passes down the i omi` V the boxes E E is collected i y this cup II.` "In the bottom of this,` cupgare` two holes 12 through which the oil findswitsjwaytothely.; lip z'. From `this,`the oil falls `into thecon` centric cup I which is cast upon, and forms a part of the lower headof the rolleror` cyll inder A, asf` seen at` C. y The circumference of this cup, beinggreater than the lipji, of

the cup,H,-it follows, that all the oil that y drips from z', must fallvinto the lower cup I. l

i This cup is also furnishedwith two'lioles 0, 0, for the'passageof the oilto the boxes.` below them, `but it is first collected in an elongated cup J which Valso encircles the shaft B, but isstationary, beingcajst upon, and forming a part` of the bed plate K. L represents the lower box. 4This is `alsoadjust-able by means of the setscrew M. ".Upon the side of the shaft Oppositeffthis box," isla chamber N, in which fis placed "waste cotton or other fibrous 'substance incontact` with the journal, for the if, purpos of retaining the oil, which lwould. other y ,y mmediately 'escape through the h` leu, which is designed` y for the exit of thewornout a dfspent oil.`

It will be understooh` that 1 sugar mil the pressure upon the rollers or cylindersis always outward, consequently, the boxesrE and L have to sustain the principal pressa and need adjustment, to keep theface:` the rollers in sufficiently close "contact, the"` y fore, the packing in the chamberyN, serves to keep upa constant lubricationwoflt box L. It will also be understood thatea `roller has a gear wheel as seenatfILaand that motion is communicatedfrom-thatone" to whichthe power isapplied,lt'c` "theoth respectively, by means of` such gear w that I claim asf my improvemen and desire to secure by` Letters Patent,

l. The concentric `cups II and Iuponmg` `the upper sides of the heads Cf, the `-same being furnished with the openings e, and 0, `for the conveyanceof. the `oilffronithe i1 l per box to the stationary cup J, `which si rounds the shaft upon the lower bedplatei 2. In combination with the cups J, sub stantially as described for the purpose here in set forth. l 9
